Definitions

  • U.S. Patent 4,990,557 disclosed the preparation of mechanically stabilized compatible blends of TPU and an at least mostly crystalline polyolefin by a high shear mixing of a melt of these polymers.
  • thermoplastic molding composition in accordance with the present invention comprise
  • thermoplastic polyurethanes suitable in the preparation of the inventive composition are known and are commercially available, for instance, under the Trademark Texin, from Bayer Corporation.
  • the suitable TPU has a melt flow rate of about 4 to 100, more preferably 10 to 90 g/10 min., per ASTM D-1238.
  • These resins are prepared by reacting a suitable polyol, polyisocyanate and a chain extender in methods which have long been documented in the relevant literature.
  • polystyrene resin it is not unusual, and in some cases it might be advantageous, to employ more than one polyol.
  • additional polyols are polyester polyols, hydroxy terminated polycarbonates, hydroxy terminated polybutadienes, hydroxy terminated polybutadiene-acrylonitrile-copolymers and hydroxy terminated copolymers of dialkyl siloxane and mixtures in which any of the above polyols are employed as a minor component (less than 50% relative to the weight of the mixture with polyether polyols).
  • the preferred embodiment entails polyether polyol alone.
  • any of the organic, aliphatic polyisocyanates preferably diisocyanates which are known in polyurethane chemistry, may be used in preparing the TPU of the present invention.
  • Illustrative of such isocyanates are hexamethylene diisocyanate, isophorone diisocyanate, methylene bis(cyclohexyl isocyanate) as well as the 4,4 -isomer, 2,4 -isomer and mixtures thereof, cyclohexylene diisocyanate, as well as its 1,2-isomer, 1,3-isomer, and 1,4-isomer, 1-methyl-2,5-cyclohexylene diisocyanate, 1-methyl-2,4-cyclohexylene diisocyanate, 1-methyl-2,6-cyclohexylene diisocyanate and 4,4 -isopropylidene bis(cyclohexyl isocyanate).
  • diols are 1,4-butanediol, 1,6-hexanediol and 1,4-cyclohexane dimethanol.
  • chain extenders which can be used in preparing TPU are adducts obtained by an aliphatic diol or triol such as 1,4-cyclohexane dimethanol, neopentyl glycol, hexane-1,2-diol, ethylene glycol, butane-1,4-diol, trimethylolpropane, and the like, with caprolactone in a mole ratio of from 0.01 to 2 moles of caprolactone per mole of diol or triol.
  • the equivalent proportions of polymeric diol to said extender can vary considerably depending on the desired hardness for the TPU product. Generally, the proportions fall within the respective range of from about 1:1 to about 1:20, preferably from about 1:2 to about 1:10. At the same time, the overall ratio of isocyanate equivalents to equivalents of active hydrogen containing materials is within the range of 0.90:1 to 1.10:1, and preferably, 0.95:1 to 1.05:1.
  • Such catalysts include organic and inorganic acids salts of and organometallic derivatives of bismuth, lead, tin, iron, antimony, uranium, cadmium, cobalt thorium, aluminum, mercury, zinc, nickel, cerium molybdenum, vanadium, copper, manganese and zirconium, as well as phosphines and tertiary organic amines.
  • organotin catalysts are stannous octoate, dibutyltin dioctoate, dibutyltin dilaurate, and the like.
  • Representative tertiary organic amine catalysts are triethylamine, triethylenediamine, N,N,N',N'-tetramethylethylenediamine, N,N,N'N'-tetraethylethylenediamine, N-methylmorpholine, N-ethylmorpholine, N,N,N'N'-tetramethylguanidine, N,N,N'N'-tetramethyl-1,3-butanediamine, N,N-diemthylethanolamine, N,N-diethylethanolamine, and the like.
  • the amount of catalyst employed is generally within the range of about 0.02 to about 2.0 percent by weight based on the total weight of the reactants.
  • compositions in accordance with the invention exhibit improved properties as compared with the base resin.
